We are given sides of the rectangle AB = (2x+1) and
AD = 4x.
Area of rectangle = Length × Width
Area = 4x(2x+1).
Distributing 4x over (2x+1), we get
and
Therefore, Area = .

Answer:
Step-by-step explanation:
We know that the line has a slope of 2 and it passes through the point (3, -4).
So, we can use the point-slope form:
Where m is the slope and (x₁, y₁) is a point.
So, let’s substitute 2 for m and (3, -4) for (x₁, y₁). This yields:
Solve for y. Distribute the right:
Subtract 4 from both sides. Therefore, our equation is:
Assuming you want the equation in slope intercept form, you first need to use slope formula to find the slope.
Plug in the coordinates that you have, (3,-1) and (4,7), for the x and y values respectively.
Which reduces to 8/1=8.
The slope of your equation is 8.
Slope intercept form is: y=mx+b. m is your slope and b is your y-intercept, x and y stay unchanged.
Plug the slope in:
y=8x+b.
Now, you can plug one of the sets of coordinates into the x and y of the equation to find b. I'm using (3,-1).
-1=8(3)+b
-1=24+b
Subtract 24 from both sides.
-25=b
Now plug this into the equation!
y=8x-25 is your final equation.

Answer:
40000
Step-by-step explanation:
Simple interest (I) is calculated as
I =
P is the amount borrowed , R is the interest and T the time in years
Here I = 2000 , R = 5 and T = 1 with P to be found , then
2000 = ( multiply both sides by 100 )
5P = 200000 ( divide both sides by 5 )
P = 40000
